The resistance to fluid mobility in the interstitial fluid spaces has been measured between perforated catheters inserted into the subcutaneous abdominal tissues of the dog and between perforated capsules implanted in the tissues 1 month previously. When the pressures in the catheters or perforated capsules were less than atmospheric pressure, the resistance to fluid movement was almost infinit...

Purpose: To discuss aspects of the pathogenesis of glaucomatous optic neuropathy based on morphologic findings of the glaucomatous optic nerve head and examinations of the cerebrospinal fluid pressure. Methods and results: Findings were: normal pressure and high intraocular pressure glaucoma eyes can show a similar appearance of the optic nerve head. These features are not found in any (other) ...

Optimization of drilling fluid parameters such as mud weight, salt concentration, and temperature is essential to alleviate instability problems during drilling through shale sections. The selection of suitable mud parameters can benefit from analyses that consider significant instability processes involved in shale-drilling–fluid interactions. This paper describes the development of analytical...

The movement of fluid and solutes across biological membranes facilitates the transport of nutrients for living organisms and maintains the fluid and osmotic pressures in biological systems. Understanding the pressure balances across membranes is crucial for studying fluid and electrolyte homeostasis in living systems, and is an area of active research. In this study, a set of enhanced Kedem-Ka...

A mathematical model of interstitial fluid flow is developed, based on the application of the governing equations for fluid flow, i.e., the conservation laws for mass and momentum, to physiological systems containing solid tumors. The discretized form of the governing equations, with appropriate boundary conditions, is developed for a predefined tumor geometry. The interstitial fluid pressure a...

oxygen is an essential part of the most important metabolic pathways in aerobic organisms. oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. increasing intra-abdominal pressure (iap) has been shown to reduce liver b...

KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...

retrospective and prospective studies looking at the role of cerebrospinal fluid pressure (csfp)/intracranial pressure (icp) have stimulated new theories and hypotheses regarding the underlying causal events for glaucoma. most recently, studies supporting a low csfp/icp as a risk factor for glaucoma have been published. this review summarizes the current understanding of csfp/icp and its potent...

The accurate prediction of wellbore temperature distribution helps to accurately estimate well pressure profile and bottom-hole pressure (BHP) which is important in the under-balanced drilling (UBD) operation. In this paper effect of temperature variation due to heat transfer of drilling fluid with the formation and also oil and gas production from the reservoir into the annulus in under-balanc...
